1. Software Preparation

2. High Level Goals Ensure scalability on 24 nodes Try to eliminate known bugs Faster program startup Better process management Better monitor management Activity logging and error reporting Avoid heavy engineering

3. What do we really want to show? Our usual application demo suit –2D, 3D, video, windowing system Input mechanism –can we get hand recognition to work? –Multi-input routing Display nodes management –keyboard/mouse, process creation/destruction –logging

4. Applications Image Viewer (1 person 2 days) –make sure it does scaling internally –eliminate that bug –timing may change due to network latency OpenGL (1 person a few days) –test on 24 nodes Walk-through: needs faster load time Iso-surface demo (on-going)

5. Low-level System Support Communication (1 person 3 days) –VMMC running for 24 nodes –Ethernet-based barrier may need tuning File System (on-going) –broadcast-based collective IO Program Synchronization(on-going) –a few OpenGL and walkthrough demos –iso-surface demo

6. Input Mechanism We really need something cool –multi-input routing (1 person 1 week) Hand recognition (2 people 2 weeks) –need a few reflective strips –more cameras and PCs Voice recognition (1 person, 1/2 week) –works, but needs a better message protocol

7. Display Management Put everything into one program Faster process creation –tree-based broadcast (1 person 1 day) Keyboard-mouse server –cut/paste existing code (1 person 1-2 days) Information logging –need a standard message format –program write to stdout

8. Information Logging Motivation –error reporting, debug information –user study (Morrow Pettigrew) Logging data path: (1 person, 2 days) –program => stdout => process server => disk –may need a globally synchronized clock serialize events

9. A Plan 24-node cluster ready (1st week April) –triple-boot: NT 4.0, NT 2000, Linux we can get Vijay, need a supervisor Test VMMC on NT 2000 (April 15) Software tests by the end 3rd week of April
